The JP138 is John Packer's rotary valve Bb/C trombone featuring a short slide design enabling younger players to achieve the whole range of notes via its ascending C rotary valve. This helps players with smaller hands to achieve the 6th an 7th slide positions of a regular Bb trombone. The JP138 also features an ergonomic thumb rest/trigger helping players to get acquainted with holding and playing a trombone. Well respected for creating affordable yet well designed and durable instruments, JP Musical Instruments has earned the respect for many in the UK education system and continues to surprise professional players with the quality and performance of their range of brass and woodwind.

The JP138 Bb/C Trombone is supplied with a JP601 mouthpiece and lightweight case. The case is well designed and attractively styled with eye catching colours and a reflective safety strap and ergonomic carry handle. The case also includes a small external storage pocket enabling players to store small accessories and sheet music with their instrument.

All JP Instruments are covered by a comprehensive 2 year warranty against manufacturing defects.
